High quality Injection Resins and Accessories products

Injection resins are specialised materials used to repair and strengthen cracks, voids, and other gaps or damaged areas in concrete and masonry, and to stem or eliminate leaks through joints or structural defects of earth-retaining structures.

Sealing active leaks is often a two-stage process, first utilising high-foaming resins to stem and control the flow. A permanent seal is then achieved by injecting low-viscosity resins at high pressure that pass through and around the foam to complete the process.

Hybrid injection resins are also available, which foam when in contact with water but can be injected deep into the joint to complete the repair without foaming.

Types of Injection Resins

The three main types of resins each possess different qualities that can be utilised depending on the project requirements:

Polyurethane (PU) resins are suitable for both temporary and permanent water sealing, reacting quickly in contact with water.

Acrylic resins are better suited for sealing deep into the cracks or joints as they can be better controlled than PU resins and are generally lower viscosity. This makes them ideal both for injection hose systems, and for permanently sealing fine cracks and joints

Epoxy resins are suitable for structural repairs and for repairing dry cracks where there is no water

Applications for Injection Resins

Injection resins are suitable for sealing leaks, repairing structural defects and sealing construction joints in basements, underground parking, tunnel projects, wall/floor transitions, concrete slabs, bridges, construction sites and lift pits, amongst other forms of construction.

Frequently Asked Questions About Injection Resins and Accessories

What are concrete injection resins, and what are they used for?

Concrete injection resins are specialised materials designed to repair cracks, voids, and leaks in concrete structures. They are injected into cracks and voids under pressure to fill and seal them, restoring structural integrity and preventing water infiltration.

When should I use concrete injection resins?

Concrete injection resins are used in various applications, including repairing cracks in concrete walls, floors, bridges, tunnels, dams, and other structures. They are also used for waterproofing applications to seal leaks in concrete basements, foundations, tanks, and other below-grade structures.

What types of concrete injection resins are available?

There are several types of concrete injection resins available, including epoxy injection resins, polyurethane injection resins, and acrylic injection resins. The choice of resin depends on factors such as the type of crack, structural requirements, and environmental conditions.

How do I inject concrete resin into cracks or voids?

Concrete resin injection is typically performed using specialised injection equipment, such as injection pumps, ports, and packers. The resin is mixed according to manufacturer’s instructions and injected into the crack or void under pressure, starting from the lowest point and working upward to ensure complete filling.

Can concrete injection resins be used for structural repairs?

Yes, concrete injection resins are commonly used for structural repairs to restore the integrity of concrete structures compromised by cracks, voids, or other defects. Properly injected resins can strengthen and reinforce damaged areas, extending the service life of the structure.

Do concrete injection resins provide waterproofing?

Yes, concrete injection resins are effective for waterproofing applications, as they penetrate cracks and voids in concrete and form a watertight seal when cured. They help prevent water infiltration, mitigate moisture-related damage, and protect against corrosion of embedded reinforcement.
